Abstract: Method for one of adjusting (taring) or re-calibrating an apparatus that includes a liquid-filled previously pressurized flexible tube that is closed at one end and is connected to a pressure sensor at an other end. Method includes activating predetermined controlling functions by establishing a differential of an external pressure exerted onto the tube by a person and a pressure prevailing in the previously pressurized tube. In establishing the differential, the method includes taking into account variations of the pressure prevailing in the previously pressurized tube, when no external pressure is being exerted on the tube by the person, due to at least one variable external ambient parameter.

Abstract: A hydraulic load cell configured to allow direct readout of an applied force in pounds by a standard hydraulic gauge, which is normally calibrated in pounds per square inch. A load is applied generally to the end of the load cell's piston. The piston is fitted with an o'ring in its machined groove and inserted into a fluid filled cylinder; the cylinder having been machined to a tightly controlled diameter of nominally 1.12838 inches. The fluid cavity is joined by a small bore tube to the hydraulic gauge. The three piece device and adjoined gauge is extremely rugged. Pascal's Law of incompressibility of a liquid and the equation of Force=Pressure×Area are utilized to realize the invention's unique simplicity and usefulness. Applications to single and multiple point loading are shown.
